I'm creating a Chat application, i have done one-to-one chat, but unable to approach how to create chatRoom and add people.
I think this link will give you call the necessary information:
http://xmpp.org/extensions/xep-0045.html.
In simple terms varying the resource while logging in to the server allows multiple users to be affiliated to a single login i.e. the single login does the work of a chat room.
You can easily create group for group chat.
Use below function for create group
-(void)joinMultiUserChatRoom:(NSString *)RoomName
XMPPRoomHybridStorage *xmppRoomStorage1 = [XMPPRoomHybridStorage sharedInstance];
XMPPJID *chatRoomJID = [XMPPJID jidWithString:RoomName];
xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:xmppRoomStorage1 jid:chatRoomJID];
[xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
[xmppRoom activate:xmppStream];
NSXMLElement *history = [NSXMLElement elementWithName:#"history"];
[history addAttributeWithName:#"maxstanzas" stringValue:#"1"];
[xmppRoom joinRoomUsingNickname:self.xmppStream.myJID.user history:nil];

I am developing Chat Application using XMPPFramwwork in iPhone.I successfully completed one to one chat,now i want to develop multiuser chat in my application.
I tried the fallowing code but any delegate methods of XMPPRoomDelegate are not called.how can i start to create chat room.When and how the roomdelegate methods get called....any reply thanks inadvance.
XMPPStream *xmppStream = [[XMPPStream alloc] init];
XMPPRoomCoreDataStorage *xmppRoomStorage = [XMPPRoomCoreDataStorage sharedInstance];
XMPPJID *roomJID = [XMPPJID jidWithString:#"vvreddy50#gmail.com"];
xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:xmppRoomStorage jid:roomJID dispatchQueue:dispatch_get_main_queue()];
[xmppRoom activate:xmppStream];
[xmppRoom fetchConfigurationForm];
[xmppRoom configureRoomUsingOptions:nil];
[xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];
[xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
Two problems:
XMPPFramework is mostly asynchronous. That means you need to call -fetchConfigurationForm after you've authenticated, in your -xmppStreamDidAuthenticate: method.
If those two calls need to be made in sequence, then call -configureRoomUsingOptions in -xmppRoom:didFetchConfigurationForm:.
Nothing at all will happen unless you call -connect: on the stream. Make sure to implement -xmppStreamDidConnect: and initiate authentication with the server in that method.
I am developing chat application using xmpp client. I can send and receive message when I login with one account. My problem is when i login with two different account i cannot send message using First login account. For sending message i tried the fallowing code:
- (void)sendMessage:(id)sender
{
xmppStream=[[self appDelegate] xmppStream];
NSString *messageStr =messageField.text;
if([messageStr length] > 0)
{
NSXMLElement *body = [NSXMLElement elementWithName:#"body"];
[body setStringValue:messageStr];
NSXMLElement *message = [NSXMLElement elementWithName:#"message"];
[message addAttributeWithName:#"type" stringValue:#"chat"];
[message addAttributeWithName:#"to" stringValue:jidStr];
[message addChild:body];
NSLog(#"%#",message);
}
}
In this delegate method, i create stream object like fallowing
-(void)setUpStream
{
XMPPStream *xmppStream=[XMPPStream alloc] init]
}
when i second time login with another account then xmppStream object is associated with second account but not for First account.
so i can't send message using first account.can any one solve my problem plz and how to create two xmppStream objects for two accounts;
The easiest way to do this is to create to xmppStream objects in your AppDelegate.
Call one xmppStreamOne and xmppStreamTwo.
You could even create an NSMutableArray of xmppStreams if you intent to log into many different different servers.
When you retrieve the xmppStream from the AppDelegate make sure to grab the right one.
I'm trying for group chat in iphone,am able to use single chat successfully.
I have created new room using following code successfully.
XMPPRoomCoreDataStorage *rosterstorage = [[XMPPRoomCoreDataStorage alloc] init];
XMPPRoom *xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:rosterstorage jid:[XMPPJID jidWithString:#"viratsroom#conference.praveens-mac-mini.local"] dispatchQueue:dispatch_get_main_queue()];
[xmppRoom activate:[[self appDelegate] xmppStream]];
if ([xmppRoom preJoinWithNickname:#"viratsRoom"]) {
NSLog(#"room created");
[xmppRoom joinRoomUsingNickname:#"viratsroom11" history:nil];
}
[xmppRoom fetchConfigurationForm];
[xmppRoom configureRoomUsingOptions:nil];
[xmppRoom addDelegate:[self appDelegate] delegateQueue:dispatch_get_main_queue()];
now under users in this group there is one user shown on openfire server which is correct.
my questions are,
1)where and how to handle invitation message to join group?
2)I have tried to join the same group made above by using following code
XMPPRoomCoreDataStorage *rosterstorage = [[XMPPRoomCoreDataStorage alloc] init];
XMPPRoom *xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:rosterstorage jid:[XMPPJID jidWithString:#"viratsroom#conference.praveens-mac-mini.local"] dispatchQueue:dispatch_get_main_queue()];
[xmppRoom activate:[[self appDelegate] xmppStream]];
[xmppRoom joinRoomUsingNickname:#"viratsroom11" history:nil];
[xmppRoom fetchConfigurationForm];
[xmppRoom configureRoomUsingOptions:nil];
[xmppRoom addDelegate:[self appDelegate] delegateQueue:dispatch_get_main_queue()];
the room name now is shown in my offline users list.
now users under this room on openfire server should increase to two as one more user has joined this room but it still shows only one previous user member.
Am I missing something? any mistake in code ? please help!
Thanks .
I got this,
Room wasnt configured properly hence all problems
calling this immediately after creating room doesnt work-
[xmppRoom fetchConfigurationForm];
[xmppRoom configureRoomUsingOptions:nil];
it takes a little time to create room after that u can configure the room.
[self performSelector:#selector(ConfigureNewRoom:) withObject:nil afterDelay:2];
:)
I receive messages from a Google Talk account, they are shown in the Table View in the Ios emulator, but when i send it, it is not shown in the Google Talk client (in another computer). This is the code:
-(IBAction)sendchat:(id)sender
{
General *general = [General sharedManager];//It is a singleton class used to store some values that need to be accesible in the whole application.
NSXMLElement *body = [NSXMLElement elementWithName:#"body"];
text=[mensaje text];
NSLog(#"Texto en el body: %#", text);
[body setStringValue:text];
NSArray *dest=[general.firstfrom componentsSeparatedByString:#"/"];//in firstfrom is stored the account from wich we receive the first message. This app cannot start a conversation itself, must only answer
NSLog(#"Destination trimmed: %#", [dest objectAtIndex:0]);//Here, the destination account shows correctly (without the /xxxx stuff, just name#gmail.com)
XMPPMessage *mens=[[XMPPMessage alloc]init];
[mens addAttributeWithName:#"body" stringValue:text];
[mens addAttributeWithName:#"sender" stringValue:general.userlogin];
NSLog(#"text vale: %#", text);
NSXMLElement *messagetosend = [NSXMLElement elementWithName:#"message"];
[messagetosend addAttributeWithName:#"type" stringValue:#"chat"];
[messagetosend addAttributeWithName:#"to" stringValue:[dest objectAtIndex:0]];
[messagetosend addChild:body];
NSLog(#"We are sending to: %#", [dest objectAtIndex:0]);
[self.xmppStream sendElement:messagetosend];
[self xmppStream:xmppStream didReceiveMessage:mens];//manage the sent message as it was received, to show it in the Table View
self.mensaje.text=#"";
}
As I say, messages are received perfectly, but I cannot send. Ive seen plenty of examples of how to send, and they are like my code. If i debug sender it is shown ok (namesender#gmail.com), and the "to" attribute is ok too (namereceiver#gmail.com). The xmppStrem is set correctly (as far as i know):
xmppStream = [[XMPPStream alloc] init];
[xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];
In ViewDidLoad method.
Any help? Thank you.
---EDIT---
I forgot to say, both accounts know each others and in the Google Talk client, the presence is sent.
I found the answer. I had two classes receiving messages, because Class A must receive a message to trigger the pushing of the view of the class B (this app is unable to start a chat conversation by itself). So, i set two xmppStream, one for every class. I put an xmppStream in my General class, make both classes take that xmppStream, and it now sends messages.
I am developing a XMPP based chat application for iOS. One of the features of the app is that i need to block some of the users from my rooster.Is there any method available to this in the XMPP framework ? If not, is there some work around to do this ?
Also can some one help me in sending images from one user to other using XMPP ?
There are a number of things you might want to consider:
Likely your user is subscribed to the contact's presence and vice-versa. He will unsubscribe from the contact's presence (so he will no longer receive presence notifications from him) by sending:
<presence to='contact#example.com' type='unsubscribe'/>
He will revoke subscription to his own presence from the contact by sending:
<presence to='contact#example.com' type='unsubscribed'/>
Finally you can remove the item from your roster.
<iq from='user#example.com/home' type='set' id='roster'>
<query xmlns='jabber:iq:roster'>
<item jid='contact#example.com' subscription='remove'/>
</query>
</iq>
In fact, if you send the stanza above, i.e. if you want to cancel both subscriptions, you do not need to send the presence stanzas, they will be handled by the servers.
Finally, you can now block further interaction with the user by means of the jabber:iq:privacy API. This is explained in detail here.
The general presence/roster management is explained in the same rfc, probably best here.
Please check this code to implement user blocking:
-(void)blockUser{
XMPPIQ *iq = [[XMPPIQ alloc]init];
NSString *from = [NSString stringWithFormat:#"from#mail.com/resources"];
[iq addAttributeWithName:#"from" stringValue: from];
[iq addAttributeWithName:#"type" stringValue:#"set"];
NSXMLElement *block =[NSXMLElement elementWithName:#"block" xmlns:#"urn:xmpp:blocking"];
NSXMLElement *item = [NSXMLElement elementWithName:#"item"];
[item addAttributeWithName:#"jid" stringValue:#"to#mail.com/resources"];
[block addChild:item];
[iq addChild:block];
[xmppStream sendElement:iq];
}
- (void)setupXMPPPrivacy
{
NSLog((#"%s [Line %d] "), __PRETTY_FUNCTION__, __LINE__);
//Init XMPPPrivacy List
//xmppPrivacy = [[XMPPPrivacy alloc] init];
xmppPrivacy = [[XMPPPrivacy alloc] initWithDispatchQueue:dispatch_get_main_queue()];
//Activate xmpp modules
[xmppPrivacy activate:[[self appDelegate] xmppStream]];
//Delegate XMPPPrivacy
[xmppPrivacy addDelegate:self delegateQueue:dispatch_get_main_queue()];
[xmppPrivacy retrieveListWithName :#"Block_List"];
}
-(void)privacyblock
{
[xmppPrivacy retrieveListWithName:#"Block_List"];
[xmppPrivacy setActiveListName:#"Block_List"];
NSXMLElement *privacyElement = [XMPPPrivacy privacyItemWithType:#"jid" value:xmpp_jid action:#"deny" order:1];
[XMPPPrivacy blockIQs:privacyElement];
[XMPPPrivacy blockMessages:privacyElement];
[XMPPPrivacy blockPresenceIn:privacyElement];
[XMPPPrivacy blockPresenceOut:privacyElement];
NSLog(#"-------> PRIVACY ELEMENT: %#", privacyElement);
[arrayPrivacy addObject:privacyElement];
[xmppPrivacy setListWithName:#"Block_List" items:arrayPrivacy];
